DANGER

WARNING
• See General Warnings on page 1-1.
• Fuel may be under pressure. Use extreme caution when disconnecting fuel line to prevent the spray of
fuel onto hot engine. See Relieving Fuel Pressure on page 23-2.
• To prevent damage to the ECU, never mix the black and gray connectors that attach to it. The black
connector is tethered to the ECU mounting plate to help prevent accidentally installing it in the gray
port.
